Story Highlights

A Mount Vernon man accused of hitting a police officer with a car last month and then fleeing, sparking a massive manhunt, was arraigned Tuesday on charges stemming from the incident, authorities said.

Leroi Bouche, 27, faces a maximum sentence of twenty five years in prison after he struck the Yonkers police detective, who was seriously injured and spent several days at Jacobi Medical Center in the Bronx, the Westchester County District Attorney's Office said.

Bouche had been indicted by a grand jury on Thursday.

The detective, a 14-veteran who suffered a dislocated shoulder and fractured vertebrae, was attempting to make a car stop on June 6 along with other members of the Westchester District Attorney's Narcotics Initiative.

He ordered Bouche to stop his vehicle, but Bouche instead accelerated and struck the police officer in a Mount Vernon parking lot, authorities said.

The incident led to the lockdown of schools in both Mount Vernon and Pelham for several hours.

Bouche, of Sheridan Avenue, fled the scene on foot and was arrested five days later in the Bronx. He was sent without bail to the Westchester County jail; a judge continued that arrangement on Tuesday.

Heis charged with six felonies in a 10-count indictment, including aggravated assault on a police officer, first-degree assault, and assault on a police officer. He also faces charges of second-degree assault, second-degree criminal mischief, leaving the scene of an incident without reporting, and personal injury.

The suspect's criminal background includes a pending drug case, a conviction on a charge of unlawful and forcible confinement of his girlfriend in 2009, and an arrest on a murder charge of which he was acquitted.
